Our take on the Kicker 40CWS104

by John Pollard
Kicker

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Legendary bass, awesome price

If you're looking to add some boom to your car's sound system, Kicker's CompS line will get your car shaking without draining your wallet. These subs are the latest in the legendary Kicker Comp line that started way back in 1986, with a proven pedigree when it comes to delivering powerful bass.

The heavy steel basket cuts down on unwanted vibrations.

Kicker technology at work

Kicker's 40CWS104 10" subwoofer features a flex-resistant polypropylene cone for hard-hitting lows without distortion, while the ribbed foam surround promotes long excursion and helps to keep the cone on target. The sub's steel basket provides a reliable foundation for big bass, and its extensive venting ensures long-lasting performance that won't break down when the bass gets heavy.

Easy to add to nearly any setup

This sub handles up to 300 watts RMS to bring out the depth your music's been missing, and its 4-ohm impedance makes it compatible with just about every amplifier on the market. This versatile sub works well in sealed or ported enclosures, and it's even suitable for free-air applications.

Subwoofer Features
Enclosure Compatibility

Subwoofer Features

Ribbed Surround: The optimized ribbed polyurethane helps eliminate flex and distortion.

Spiralead Tinsel Leads: The durable Spiralead tinsel leads are woven into the woofer's spider, for added strength and reliability.

Steel Basket with Vented Pole Piece: The steel basket's vented pole piece and Kicker's Quad Venting slots contribute to the woofers' efficient cooling and durability.

Speaker Terminals: Each speaker terminal has two 0.25" push-on terminals (crimp-on quick slides included).

Enclosure Compatibility

Enclosure Versatility: The Kicker Comp subwoofer is versatile, performing well in vented or sealed enclosures, and in free-air applications.

Sealed Enclosures: A sealed enclosure design offers the smoothest response, with increased energy at the lowest frequencies (between 20 to 30 Hz).

  • Minimum enclosure volume: 1.0 ft³
  • Maximum enclosure volume: 2.4 ft³

Ported Enclosures: A ported (vented) enclosure design is typically more efficient than a sealed enclosure.

  • Minimum enclosure volume: 1.25 ft³ with a 1.5" x 10.5" slot port opening that is 14.5" deep
  • Maximum enclosure volume: 1.75 ft³ with a 1.5" x 10.5" slot port opening that is 13.25" deep

Infinite Baffle Mounting: The Kicker Comp subwoofers are also designed to be used as free-air drivers. The infinite baffle mounting method effectively utilizes the trunk of a sedan as the enclosure.

Big bang for the buck!

Written By Joe, Palenville, NY on Friday, August 08, 2014
Crutchfield Customer Review (What's this?)
 
Going from a 12" Xplod in an enclosure to 2 of these mounted open air into a sheet of plywood in the space behind my back seats (my seats fold down to give access from the trunk). The difference is night and day. I finally have as much bass as I want!
Pros:
Inexpensive, solid build, comes with crimp connectors, two sets of positive and negative terminals for easy wiring in parallel
Cons:
None

Great boom for the buck

Written By Todd, TX on Monday, June 30, 2014
Crutchfield Customer Review (What's this?)
 
Installed in my daughters impala. One single sub gives off a great sound without being to obnoxious. If I had it in a box with the correct dimensions Id imagine it would sound even better.
Pros:
Great bass for music without being overly deep.
Cons:
None
